Abstract

The utility model relates to a mobile type support tower for erecting bridges, which is suitable to use for the construction of a big-scale work. Bottom parts of a construction 10 on both sides are provided with slide ways 20 for provided with a main steel frame 30, and the main steel frame is provided with a platform 31 for provided with an auxiliary steel frame 40. The bottom of the auxiliary steel frame 40 is provided with pulley wheels 41 which transversely move on the platform 31. A supporting base 50 is arranged between two pulley wheels, and the top face of the supporting base is connected with the platform. Through the auxiliary displacement structure, the auxiliary steel frame can be moved to the supporting base from the platform; the auxiliary steel frame and the main steel frame make use of a jack mechanism to support the construction object together. When the construction is completed by the construction object, the jack is reset and the auxiliary steel frame is placed inside the main steel frame. The whole group of steel frame on the slide way is moved to the lower part of next construction object. The utility model can avoid artificial consumption, save the time of disassembly and assembly of the steel frames, and greatly improve the efficiency of construction.

Description

The movable type bridge support tower

The utility model relates to a kind of movable type bridge support tower that is used for major works.

At present, major workss such as bridge are when construction, be that pre-putting on the shelf prior to the relative ground of bridge pier established steelframe, be used for supporting a bridge section of casting, when the bridge section that is supported on the steelframe and fixed end finish link construction after, promptly need steelframe is removed, be carried on the relative ground of next bridge section and assemble, the construction works that is beneficial to next bridge section is carried out.

Yet, because employed steelframe volume of this kind major works and member are all very huge and heavy, not only disassembly process is very consuming time, also can expend considerable manpower and machinery (as crane etc.), and cause construction speed slowly and the danger that increases the constructor.

The purpose of this utility model provides a kind of movable type bridge support tower that can significantly improve efficiency of construction that does not need assembly and disassembly.

For reaching above-mentioned purpose, the utility model by the following technical solutions:

The utility model mainly is to set slide rail in the both sides, bottom of construction thing, and main steel frame is arranged on the slide rail, and main steel frame is provided with platform, secondary steelframe is ccontaining on it, secondary steelframe bottom is provided with pulley can be traversing on platform, between two slide rails bearing is set in addition, and the end face of bearing is connected with platform.The auxiliary displacement structure of this kind, can be with secondary steelframe from traversing to bearing on the platform, utilize jack together support construction thing with main steel frame, after the construction thing is finished construction, jack is replied and secondary steelframe is received to main steel frame, can with put in order the group steelframe slide rail upper move on to next the construction thing below, so, can avoid labor intensive, more save the time of steelframe dismounting, significantly improve efficiency of construction, the utmost point is applicable to the construction of major workss such as bridge.

The utility model will be further described below in conjunction with drawings and Examples:

Fig. 1, Fig. 2, Fig. 3 are structure of the present utility model and implement the action front view.

Fig. 4, Fig. 5 implement the action vertical view for the utility model.

10 for construction thing, 20 be that slide rail, 30 is supporting mechanism for jack, 61 for bearing, 60 for pulley, 50 for secondary steelframe, 41 for platform, 40 for main steel frame, 31.

At first as shown in Figure 1, the utility model is to set slide rail 20 in the both sides, bottom of construction thing 10, the above main steel frame 30 of at least one tool is arranged on the slide rail 20, each main steel frame 30 is provided with platform 31, one secondary steelframe 40 is placed on the platform 31, and secondary steelframe 40 bottoms are provided with pulley 41 can be traversing on platform 31, between two slide rails 20 bearing 50 is set in addition, the end face of bearing 50 is connected with platform 31, and secondary steelframe 40 can be traversing between platform 31 and bearing 50 end faces by pulley 41.

Fig. 1 cooperates shown in Figure 4 for another example, main steel frame 30 and secondary steelframe 40 set up finish after, can cooperate by the jack 60 which is provided with and other supporting mechanism 61, together support construction thing 10, after construction thing 10 is finished construction, jack 60 and supporting mechanism 61 are replied back (as shown in Figure 2), can secondary steelframe 40 is traversing to the platform of main steel frame 30 (as Fig. 3 and shown in Figure 5) by pulley 41, can will put in order the group steelframe and be configured in slide rail 20 top offsets, so that next construction thing 10 is constructed to thing 10 predeterminated positions of constructing with respect to next.

As shown in the above description, when the utility model is desired to carry out the construction of next construction thing 10, not needing to put in order group steelframe structure is dismantled, is carried and re-assemblied, this characteristic, not only can avoid artificial expending, more save the time of steelframe dismounting, significantly improve efficiency of construction, extremely be fit to be applied to the construction of major workss such as bridge.

And be to try to achieve steelframe to construct the stability that is arranged on slide rail or the bearing, can all can set jack mechanism in main steel frame 30 and secondary steelframe 40 bottoms, be held on the ground, and this mechanism belongs to simple and easy technology commonly used, do not give unnecessary details in addition at this.

In the structure of the present utility model, can link mutually by suitable mechanism between each main steel frame 30, make the whole steelframe mechanism that organizes when displacement, only need utilize drawing machinery to be positioned at foremost main steel frame with the hawser drawing, can make the displacement smoothly of whole group steelframe, by the auxiliary displacement of drawing machinery, can make the displacement of steelframe reach more rapidly conveniently.
